4 Claims. (Cl. 15-261) This invention relates to a mop wringer for use in connection with a mop pail and an object of this invention is to provide an efficient device by which excess water can be quickly and easily pressed out of a mop with minimum effort on the part of a person using the mop and without requiring the user to put his hands in the water.

Another object is to provide a mop wringer comprising two divergent perforated plates hinged together to form a V-shaped or trough shaped receptacle and suspended in a mop pail by convergent links in a suitable position to receive a mop so that when a water saturated mop is placed between the two plates. and a downward pressure exerted thereon the plates will be caused to exert an even pressure against the mop and squeeze any desired percentage of the water out of the same.

Other objects of the invention are to provide IIlOp wringer means that is simple in construction, not expensive to manufacture, easy to use and efi'icient in itsoperatlon of removing excess water from a wet mop.

Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings.

in the drawing Figure l is atop plan view of a mop wringer constructed in accordance with this invention showing the same in a mop pail, a portion of the pail being broken away.

Fig. 2 is a view partly in section and partly in elevation looking in the direction of broken line 2-2 of Fig. 1.

Fig. 3 is a View similar to Fig. 2 showing this mop wringer as it may appear when a mop is applied thereto for wringing. v

Fig. 4 is a fragmentary perspective view of one end portion of the mop wringer.

Like reference numerals designate like parts throughout the several views.

This mop wringer comprises two rectangular plates 5 and 6 having two adjoining interfitting curved edge portions I and 8 and having four end members 9 of generally triangular shape. Preferably the plates 5 and 6 are formed of sheet metal and have drainage perforations, such as slots' lc therein. However it will be understood that these plates canbe formed of other porous material such as wire screen. The curved edge portions 1 and 8 reinforce and strengthen the plates 5 and 5 and cooperate to form a bottom that a mop will not catch in.

The two end members 9 at each end are arranged so that they overlap each other and the two plates 5 and 6 are pivotally connected with each other "by two pivot members H which extend 2 through the end members 9 at locations adjacent the curved edges 1 and 8 of the plates. This pivotally connects the two plates 5 and 6 for relative angular movement toward and away from each other on an axis parallel to the adjoining curved edge portions 1 and 8 of said plates.

Preferably at least one perforation or slot ii is provided in each'end member 9 to facilitate drainage of water.

Preferably spring means is'provided to urge the two plates 5 and 5 into a spread apart position, This spring means can be in the form of two spring wires 13 each having a medial loop portion is anchored on one of the pivot members I l and each having two outwardly bent end portions I5 which fit into holes H5 in the end membars 9 of the respective plates 5 and 6. One of these springs 13 is provided at each end of the device and said springs normally tend to hold the plates 5 and 5 in a spread apart position such as the position in which they are shown in Figs. 1, 2 and 4. The pivot members ll preferably are shouldered rivets which are long enough to function as anchor means for the loop portions 14 of the springs IS.

The top edge portion of each plate 5 and 5 is preferably rolled or bent around a reinforcing wire 3| to give added strength and provide a better finish.

The means for suspending this mop squeezing device within a mop pail ll comprises two pairs of relatively inclined links connected with the respective ends of the mop squeezing device. These two pairs of links and the parts connected therewith are herein shown to be duplicate construction and similar parts thereof are similarly numbered.

Each pair of relatively inclined links comprises two upwardly convergent link members It each havingan eye member l5 at each end. One eye member I?! of each link is connected with a O suitableeye members 20 at the uppermost corner of one of the plates 5 and 6, it being assumed that the adjoining pivotally connected edges of the plates 5 and 6 are their lowermost edges. The other eye member IQ of each link It; is connected with a mop pail engaging bracket, one such bracket being provided for supporting the two links [8 of each pair. Each mop pail engaging bracket comprises a perforated lobe 2| with which two of the links [8 engage, a normally upright portion 22 adapted to engage with the side of a pail I1 and a normally horizontal portion 23 adapted to rest on the top rim 24 of a pail ll. Each rim engaging portion 23 is provided with a fixedly secured upwardly projecting member 25, such as a rivet, on which a loop 26 of a pail engaging spring cli 21 is supported. Each spring clip 2! has two arms preferably of unequal length which extend in generally opposite directions from the loop 26 and are approximately parallel to the rim engaging portions 23. Each arm of each clip 21 terminates in a hook shaped portion 2 8 which is adapted to hook over the top -rim 24 of the pail l1. The-longer arm of each spring clip 21 is sufficiently resilient so that it can be flexed manually and engaged with or disengaged from the rim 24 of a .pail. -The shorter arm of each spring clip '27 has 'nio'restiif ness because of its short length and cooperates to firmly hold the bracket 2|, 22, 23 on the pail.

In use, this device is suspended in a mop pail a 4 portions pivotally connected respectively with the two plates near the upper edges of the plates and said two links of each pair converging upwardly and being supported by the pail from their upper end portions whereby downward pressure of a mop in the V-shaped receptacle between said plates will presssaid platesagainst the mop.

3. A mop wringer for'use in amoppail comprising two rectangular perforated plates positioned at a divergent angle relative to each other with twolower edge portions thereof adjoining to 'pro'vide a -V-'shaped mop receptacle between in the manner shown in Figs. 1,2 and 3. n'n op; which may comprise water absorbent material l 29 carried by a platen 30, Fig. 3, is dipped in water in the pail H. The water saturated material 29 is then placed-in the V-shaped'receptacle between the plates 5 and Band a downward pressure is exerted against the platentfl. This tends to press the water saturated-material-29 downwardly and at the same time the-increased load to which the plates 5 and -6 and the two pairs of divergent links I 8 are subjected tends to move the plates 5 and 6 toward each other. Thus the absorbent part 29 of themop is compresseddownwardly by the platen-38 and is compressed sidewiseby the plates 5 andG-and any desired percentage of the water itcarries is evenly squeezed out of the absorbent material.

The foregoing description anda'ccompanying drawings clearly'dis'clos'e a preferred'embe'diment of this invention but-it will bra-understood that this disclosure -is'merely illustrative and :that changes can be made (within the'scope of the following claims.
